Problems solved by technology

As we all know, usually the authenticator entity and the authentication requester entity in some applications have weak computing power, and the public key calculation is time-consuming, which will form a network access bottleneck, and the operation efficiency of the protocol is low, especially in public wireless LANs In the case of frequent switching of PWLAN (PublicWLAN) roaming, the operating efficiency of the protocol will be even lower

Embodiment Construction

[0019] The specific flow of the WAPI certificate identification method of the present invention is as follows:

[0020] 1) When the authentication requester entity associates or re-associates with the authenticator entity, the authenticator entity sends an authentication activation packet to the authentication requester entity, and the authentication activation packet includes an authentication identifier;

[0021] 2) After the authentication requester entity receives the authentication activation packet, it sends an access authentication request packet to the authenticator entity, and the access authentication request packet includes the authentication identifier, the temporary public key of the authentication requester entity, and the certificate of the authentication requester entity and the signature of all the aforementioned fields by the authentication requesting entity using the long-term private key;

[0022] 3) After the authenticator entity receives the access authen...

Abstract

This invention relates to a discriminating method for WAPI certificates including: when a discrimination applicant entity associates or re-associates with a discriminator entity, the discriminator entity sends an activation packet to the applicant entity, which sends an accessed required packet to the discriminator entity to validate if the discriminating ID in the packet is correct, if not, it casts it off, when the service entity receives a certificate request packet, it verifies if the identities of the discriminator and the request entities are legal and feeds back a cetificate response packet to the discriminator to verify it, and the request entity verifies the accessed discrimination response packet after it receives it.

Description

technical field [0001] The invention relates to a WAPI certificate authentication method. Background technique [0002] In order to solve the security loopholes in the WEP (Wired Equivalent Privacy) security mechanism defined in the WLAN (Wireless Local Area Network) international standard ISO / IEC 8802-11, my country promulgated the National Standard for Wireless Local Area Network and its No. 1 amendment, The WLAN authentication and privacy infrastructure WAPI (WLAN Authentication and Privacy Infrastructure) security mechanism is adopted to solve the security problem of the WLAN. [0003] WAPI is an innovative security technology proposed by my country. It mainly includes two parts: WAI (WLAN Authentication Infrastructure) and WPI (WLAN Privacy Infrastructure). WAI provides security policy negotiation, user identity Functions of authentication, key agreement, and access control. The WAPI certificate authentication protocol uses public key cryptography to complete the peer-t...
